Catman..._field(3pm)

✨ NAME ✨

Catmandu::Fix::add_field — bestie, this is the fix that adds a brand-new value to a HASH key or an ARRAY index, or changes one that's already chilling there. 💖

💅 DESCRIPTION 💅

So like, <rainbow>the whole point</rainbow> — unlike its sibling set_field, this one is the generous icon. If the intermediate structures along the way don't exist yet? It literally just creates them for you. No drama, no missing-key meltdown, it builds the whole path on the way in. 🫶

Not me showing up to a key that doesn't exist and just… making it exist. Main character energy fr fr. 👑

🎀 SYNOPSIS 🎀

# Add a new field 'foo' with value 2
add_field(foo, 2)

# Change the value of 'foo' to 'bar 123'
add_field(foo, 'bar 123')

# Create a deeply nested key
add_field(my.deep.nested.key, hi)

# If the second argument is omitted the field has a null value
add_field(foo)

Obsessed with that last one tbh — skip the second argument and the field just gets a null value. Simple as. ✨
